STOVE FOR BURNING PETROLEUM.

SPECIFICATION forming part of Letters Patent No. 249,952, dated hlovemioer 22, 1881,

Application filed October 1, 1881. (No model.)

To all whom it may concern Beit known thatI, HEINRICH KooK, ot'H-amburg, in the Empire of Germany, have invented certain new and useful Improvements in Petroleum or Hydrocarbon Oookin g and Heating Stoves, of which the following is a specification.

These improvements in petroleum or hydrocarbon stoves relate to the wick tubes or holders and to details of the construction of the outer casing.

In the accompanying drawings, Figure 1 represents a vertical section ot'a stove embodying my invention. Fig. 2 is a similar section on a plane at right angles to that in which Fig. 1 is taken. Fig. 3 is a horizontal section on the line a- 00, Fig. 1. Fig. 4 is a side view of one of the wick tubes or holders. Fig. 5 is an end view thereof, and Fig. 6 is a horizontal section of one of the tubes or holders and a plan of the wick-feeders.

Similar letters ofreference designate corresponding partsin all the figures.

The stove is constructed of several parts, that are separable to permit of their being packed for transportation, and the principal parts are made of cast iron, which is both cheap and strong.

A socket or stand, A, supports by lipped edges a the reservoir or basin B, containing petroleum or hydrocarbon oil. Over said reservoir is arranged the cover-plate O, carrying the wick-feeders, burners, and wick-tubes. The body of the stove E encircles the burners, over which is the outer and upper part or crown, F, of the stove-casin g for carrying a kettle, boiler, or other object thathas to be heated.

This top part or crown F is movable vertically,

audits bottom rim, 0, has in it small grooves or notches t, which fit upon ribsr, fastened or formed on the exterior of the body or easing E of the stove, and enables the crown to be lowered, as seen in Fig.2. When the top part or crown, F, is raised, as iuFig. 1, the rim ebecomes freed from the ribs 1', and it can then be turned for a short distance to make the rim rest upon the ribs, which will support the crown F in an elevated position. The purpose of this construction is to bring the crown,

and with it the boiler or other object that has to be heated, nearer to the flame or flames, or

to increase the distance from the flame, it required.

The body or case E of the stove is kept to the stand A by means of screws b, that pass through lugs b on the bottom part and catch over the lower projecting rim, N, of the body E. The top rim, E, is attached to the body E by means of screws (1, and prevents the crown F being fully drawn off from the body; but when necessary to detach the crown from the body the rim E can be removed andthe crown lifted off said body.

Each burnerof which there may be two, or more or less, applied to each stove-consists of a bottom casing, H, cast to the cover-plate O, and a top casing, H, that serves as wick holder or tube. The top casing, H, is hinged to the bottom casing atf, and can be turned backward to open the bottom casing, but is held closed ordinarily by a screw, f. The wick-tube of the casing H is lined with tinplate Z, or other smooth sheet metal, to make its inner part quite smooth, and to prevent damaging of the wick when moved up or down in the cast-iron slot. The lining Z is secured at the top and bottom edges by foldingit over the edges of the casing H.

The wick-feeder for moving the wick up or down consists of a pair of rollers, g g, connected to each other by gear-wheels g, and moved or turned in a well-known manner by one prolongated axle, 9 The surface of the rollers forms part of the invention. Each roller is furnished with longitudinal grooves, and also circular grooves, by which a number of pyramidal teeth or sharp-pointed projections are formed on the outer circumference of each roller. The action of these rollers is to gripe and guide the wick on its whole breadth, while at the same time the grooves allow the petroleum or other liquid to pass through the grooves along the whole breadth of the rollers from the basin or reservoir B freely to the top of the burner. This wick-feeder is not here claimed, and may be made the subject of a future application for Letters Patent. The rollers g g rest in open beari n gs in the top edge of casin g H, and the top casing, H,is turned over, while they are safely kept by top casing when the latter is closed and fastened by the screw f.

For extinguishing the flame each burner may be furnished with a cap, 01, pivoted so that it may be swung or partly rotated to cover or uncover the wick-tube H.- These caps "u can be turned by rods h, which form prolongations of their pivots from outside the stove, and can be placed down to cover the flame. These caps may be constructed with an opening, 4;, at the end or other part, so that when closed over the end of the Wick-tube a small part of the flame remains uncovered and unextinguished. If the cap U is closed rapidly, the flame is extinguished altogether; but it the cap is carefully lowered down upon the flame, a small part of the wick will remain alight, and may be used for purposes where only little heat is required.

Instead of partly covering the wick, the flame may also be reduced in size by forming the upper or outer burner cap or cone, R, of each flame out of two'parts, that can be narrowed or be drawn apart from each other for reducing or enlarging the width of the opening t, through which the flame passes.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. In a petroleum or oil stove, thecombination, with a wick-tube composed of cast metal, of a lining of tin or other sheet metal for giving said tube a smooth surface, substantially as specified.

2. In a petroleum or oil stove, the combination, with an outer case or body provided with vertical ribs, of a crown or top portion adapted to besupported on the upper ends of said ribs, and provided with notches, which, when said crown or top portion is turned, are adapted to fit over the ribs and allow the crownjor top portion to be moved down, substantially as specified.
